Phase - Sleep Schedule Reset

Your sleep schedule is off. Phase shifts it back — one day at a time.

Phase is a guided program that fixes your broken sleep schedule through small, progressive daily shifts. No vague advice. No endless tracking. Just a clear plan that moves your bedtime and wake time closer to your goal — 15 minutes at a time.

Tell Phase when you currently sleep, when you want to sleep, and it builds a personalized day-by-day plan to get you there.


HOW IT WORKS

- Pick a program that fits your situation
- Set your current and goal sleep times
- Get a personalized day-by-day schedule
- Follow science-backed daily nudges
- Watch your sleep shift into place


6 SLEEP PROGRAMS

Phase is not one-size-fits-all. Pick the program that matches your situation:

- Sleep Schedule Reset — the original 14-day phase shift
- Night Owl Fix — stop going to bed at 3 AM
- Jet Lag Recovery — get back on local time fast
- Weekend Drift Reset — fix the Sunday-night-to-Monday-morning gap
- Shift Work Transition — adjust to a new work schedule
- Early Riser Challenge — become a morning person in two weeks


YOUR DAILY NUDGES

Every day, Phase gives you timed nudges based on your schedule and your local sunrise and sunset:

- Morning Light — get sunlight early to reset your internal clock
- Caffeine Cutoff — stop caffeine at the right time so it does not interfere with sleep
- Screen Dim — reduce blue light before bed to protect melatonin
- Wind Down — start your pre-sleep routine at the right moment
- Bedtime — hit the pillow at your new target time

All nudge times adjust automatically as your schedule shifts forward each day. Toggle nudges on or off and fine-tune timing to fit your life.


WIDGETS AND LIVE ACTIVITY

- Home Screen and Lock Screen widgets for sun position, nudge checklist, bedtime countdown, and sleep stats
- Bedtime Live Activity — a countdown on your Lock Screen and Dynamic Island as bedtime approaches
- Bedtime alarm that rings through Silent Mode and Do Not Disturb

HEALTHKIT INTEGRATION

Phase reads your sleep, sunlight, exercise, and caffeine data from Apple Health to auto-verify nudges and show activity bars on your daily timeline. Phase never writes to HealthKit — your data stays yours.

No charts. No dashboards. No social features. Phase does one thing and does it well — it fixes your slee
